1.1: Ruins and Remnants.

This is a fairly hefty update, as the mod goes, in which:

• Chalks other than essential chalk were overhauled heavily; there are now six chalks, they're mostly easier to make and in larger quantities, and each is more specific in use.  Basically, just re-read the Stone Book section; loads of alterations.
• There are now ruins!  They spawn on grass, so no desert ruins yet, and there's....   there's a lot.  They get their own entire Stone Book section.
• The sacrificial blade is now entirely gone, and in it's place there's four mod-specific enchantments; they also get their own stone book section.
• The wands got a repositioned model setup, so they don't look crap in the GUI now.
• Some bugfixes got implemented!  Yay!
• Probably some all-new bugs got implemented too!  *Sigh*
